CASE 5191 ABSTRACT OF THE DISCLOSURE A process and apparatus for simultaneously removing NOX and SOX from the exhasut of a furnace includes an injection of limestone into a region of the furnace having a temperature of about 2,000° - 2,400°F, and an injection of ammonia into a region in the furnace having a temperature of about 1,600° - 2,000°F. The limestone absorbs at least some of the SOX and the ammonia absorbs at least some of the NOX. The exhasut from the furnace which contains particulate and gases, is supplied to a dry scrubber where further reactions take place between unused ammonia and SOX, and calcium sorbent and SOX. Sorbent and ammonia regeneration can also be utilized to further improve the efficiency of the system.
